Is the prayer of four rak'ahs before 'Asr among the regular voluntary prayers (rawatib)?

Question:
Honorable Shaykh, may Allah grant you success, he says: Is the prayer of four rak'ahs before 'Asr among the regular voluntary prayers (rawatib)?

Answer:
No, this is purely voluntary, absolutely not among the rawatib. 'Asr has no rawatib, neither before it nor after it. As for praying four rak'ahs before it, this is mentioned in the hadith but it is purely voluntary. Yes.
